Twollow is one of those myriad of Twitter startups that’s made the rounds on most of the social media blogs and sort of faded into the background for most of us. It’s a utility designed to let you auto-follow those who mention certain keywords on Twitter.

Combined with another utility designed to pare down those stubborn individuals who absolutely refuse to follow you back like SocialToo, it’s a powerful combination that would likely explode one’s follow count and social media influence.

You don’t have to buy the service to have these benefits, but you can if you want. It’s up for auction as of today, and has a fairly low starting point given the pretty large amount of traffic it’s brokering – about 83k monthly pageviews.
